This bar is amazing! I customized mine to meet my needs. For this evening if you wanting to put a freestanding fridge in like I did just don’t enclose the back. I searched so many reviews to see if they put the fridge size so in an effort to help someone also trying to purchase this bar to add a fridge here are the perfect specs: 

1.5 cubic feet
Fridge height  - 19 2/5
Fridge width - 18 9/10
Fridge depth - 17 3/10 inches
